Until recently daydreaming was viewed as a waste of time or it {#blank#}1{#/blank#} (consider) an unhealthy escape from real life and its duties．But now some people are taking a fresh look at daydreaming．Some think it may be a very {#blank#}2{#/blank#} (health) thing to do．Some researchers are finding that daydreaming may be important to mental health．Daydreaming, they tell us, {#blank#}3{#/blank#} a good means  of relaxation．But its benefits go{#blank#}4{#/blank#} this．A number of psychologists have conducted experiments and have reached some{#blank#}5{#/blank#} (surprise) conclusion．

    Dr．Joan T．Freyberg has concluded that daydreaming contributes growth．It also improves{#blank#}6{#/blank#} (concentrate),attention span, and the ability to get along with others．Industrialist Henry J．Kaiser believed that much of his success was due{#blank#}7{#/blank#} the positive use of daydreaming．Florence Nightingale dreamed of becoming a nurse．The young Thomas Edison pictured{#blank#}8{#/blank#} as an inventor．

    For these notable achievers, it appears that their daydreams came  {#blank#}9{#/blank#}．Dr Harry Emerson Fosdick offered this advice: “Hold a picture of yourself…in your mind's eye, and you will be drawn toward it．Picture yourself {#blank#}10{#/blank#} (vivid) as defeated and that alone will make victory impossible．

    I can well remember that I was once asked to deliver a speech titled “A Real Test in My Life” before the whole class at the age of 9! You can imagine how{#blank#}1{#/blank#}(terrible) shy I was with so many eyes fixed on me. I had no choice but {#blank#}2{#/blank#}(prepare) for it, though. First of all, I was to draft the speech, {#blank#}3{#/blank#} was just a piece of cake for me, a good writer. But the hardest part {#blank#}4{#/blank#}(lie) in my oral presentation from my memory—for to read from the paper {#blank#}5{#/blank#}(forbid). The real moment began when I stood on the platform with my legs {#blank#}6{#/blank#}(tremble) and my mind blank. But my listeners were waiting patiently without any signs of rushing me. Gradually I found {#blank#}7{#/blank#} (I) back, delivering my speech without difficulty. After {#blank#}8{#/blank#} seemed to be a hundred years, I found my audience applauding—I made it! From then on, my fear of talking before the audience disappeared. Actually with my {#blank#}9{#/blank#}(confident) built up, I now turn out to be a great speaker. Looking back, I know the{#blank#}10{#/blank#}(great) difficulty on our way to success is our fear. Overcome it and we will be able to achieve our goals.

    Polar bears are suffering in a much {#blank#}1{#/blank#} (warm) world.

    Polar bears live in environments too cold for most animals. During much of the year, they live and hunt on the frozen Arctic sea ice. Nature has {#blank#}2{#/blank#} （prepare）them for the cold conditions. But nothing has prepared the bears for the danger {#blank#}3{#/blank#} threatens the only home they know.

    The polar bears' world is melting. Studies show that the amount of the polar ice {#blank#}4{#/blank#}（have）decreased by 9.8% every 10 years since 1978. Now about 20,000 to 25,000 polar bears live in the Arctic. Polar bears rely {#blank#}5{#/blank#} the sea ice for their survival. “The sea ice is more {#blank#}6{#/blank#} just this platform that the bears walk over,” says Andrew Derocher, {#blank#}7{#/blank#} scientist who studies North American polar bear populations. “{#blank#}8{#/blank#} it, they can't exist.”

    Some melting and refreezing of the polar ice is natural. But in a warmer world, these cycles speed up, and bears have less time {#blank#}9{#/blank#} (hunt). Normally, they have three months in the spring when they gain more weight. The extra fat is used later, when the bears are not {#blank#}10{#/blank#}(active) hunting.

    Last October, while tending her garden in Mora, Sweden, Lena Pahlsson pulled out a handful of small {#blank#}1{#/blank#}(carrot) and was about to throw them away. But something made her look closer, and she noticed a {#blank#}2{#/blank#}(shine) object. Yes, there beneath the leafy top of one tiny carrot was her long-lost wedding ring.

    Pahlsson screamed {#blank#}3{#/blank#} loudly that her daughter came running from the house. "She thought I had hurt {#blank#}4{#/blank#}(I)," says Pahlsson.

    Sixteen years {#blank#}5{#/blank#} (early), Pahlsson had removed the diamond ring {#blank#}6{#/blank#} (cook) a meal. When she wanted to put the ring back on later, it was gone. She suspected that one of her three daughters — then ten, eight, and six—had picked it up, but the girls said they hadn't. Pahlsson and her husband {#blank#}7{#/blank#} (search) the kitchen, checking every corner, but turned up nothing. "I gave up hope of finding my ring again," she says. She never replaced it.

    Pahlsson and her husband now think the ring probably got {#blank#}8{#/blank#} (sweep) into a pile of kitchen rubbish and was spread over the garden, {#blank#}9{#/blank#} it remained until the carrot's leafy top accidentally sprouted (生长) through it. For Pahlsson, its return was {#blank#}10{#/blank#} wonder.

    When Jennifer Lawrence tripped on her way to accept her best actress Oscar one year, her pink princess-like Dior dress {#blank#}1{#/blank#} (capture) in all its glory. The unscripted moment became hot topic throughout social media.

    That bonus air-time for a single dress at one of the world's global events is priceless for the likes of Dior, one of the {#blank#}2{#/blank#} (influential) fashion houses in the luxury marketplace.

    Success on the red carpet can earn exposure and profits for luxury brands for years {#blank#}3{#/blank#} (come). The red carpet, which will be televised live before Academy Award ceremony, presents a great opportunity for a designer to reach an audience that expands {#blank#}4{#/blank#} the fashion setting. The Lawrence dress received about 40 million mentions on various social media.

    One way of estimating the monetary benefits of having a standout dress on the red carpet is to compare how much a brand would otherwise spend on commercial advertising during the same time. {#blank#}5{#/blank#} Lawrence had only 75 seconds of solo camera time for her Oscar acceptance speech, Dior had to pay more than $4 million for a commercial spot of the same duration on similar occasions. And this didn't include the time {#blank#}6{#/blank#} (devote) to Lawrence and her dress on the pre-show televised red carpet. Lawrence, 23, had an advertising contract with Dior. {#blank#}7{#/blank#} the group's deal with Lawrence affected its sales was clearly stated in its annual financial report. That year, the group clothing section's profits {#blank#}8{#/blank#} (total)165 million euros, up 26 percent from the previous year.

    Heston, the founder of a publicity firm, {#blank#}9{#/blank#} success stories include introducing Jimmy Choo shoes and designer Saab to Hollywood, believes that the Oscar red carpet is today dominated by established luxury brands. Finding it much more difficult to compete with big brand names to dress super stars on big events, many young designers turn to {#blank#}10{#/blank#} (bet) on promising rising stars, expecting an overnight success if the young stars rise to sudden fame.
